To all whom it may concern Be it known that. I, FRANK L. MCCARTY,

a citizen of the United States, and residing My invention relates to lubricating wheels p for use on pit cars, Amine cars, trucks,lar ries, and the like..` f v y The objects of my invention are to provide a wheel ofy the Lcharacter described which embodies simplicity ofconstruction andeconomy of operation; to provide-a wheel in, which ymeansare devised for an automatic and positive lubrication; andv to provide a wheel in whichithe maximum'surface at the point of its y'connection with the axle ,is lubricated in a `thorough and .extremely convenientmanner., f

To the accomplishment of the recited objects and others4 coordinate therewith, the preferred embodiment of my invent-ionresides in that construction andv arrangement of parts hereinafter described, illustrated in the .accompanyingfdrawinga and embraced within the scope .ofthe appended claim.k

yIn said drawings :-Figure1 (isa side elevation of the wheel yembodying my invention; Fig. 2 is a central transverse sectional view of the wheel; Fig. 3 isa detail secf tional elevation of the'spring, plunger and screw plug in contracted relation, and Fig. 4- is a transverse section taken upon lines 4-4 of Fig. 2.

Broadly, my invention involves a car wheel provided with grease chambersl at diametrically opposite points, the same having passages or apertures 4communicating with the axle in such manner that the entire longitudinal extent of the latter is thoroughly lubricated. In combination. with` the grease chambers I employ a pair of force feed lubricators which insure a positive and automatic supply of the lubricant through said passages. I have also devised means for securing an expeditious adjust ment of the spring-controlled plunger which is utilized for expelling the grease from the chambers.

In said drawing the numerals 1 and 2 designate the usual types of car wheel and axle, respectively. Upon diametrically opposite sides of the wheel I provide a pair of'circ'ulargreasechambers 3, the same ter-y mmating in'rear walls as 4 and having screwl `plugs `5 adapted for engagement with their outer walls for the .purpose of confining the lubricant. At the back. and bottom of each chamber 3 there is afpassage which communicates with the periphery kof the axle 2. jAs will be found upon inspection of Fig. 2k of the drawingl the upperpassage 6 has a lcontracted portionimmediately adjacent the chamber 3 and from this point it suddenly diverges outwardlyor downwardly toward the axle, while the opposite passage 7 .is disposed outwardly at a greater angle than its complemental passage 6, whereby it will be seenthat both passages yconsidered conjunctively1 aiord broad,k openings or spaces which `are kpractically a continuation of eachother. :Communicating with the passage to the rear thereof is a horizon-y tally arrangedslot asS, which serves to convey the `grease to lthecircular packing!) which is maintained iny constant-f ycontact with the axle through the medium of `a spring yclip 10 as best seen in Figa..v l n Each screw plugy 5 is equipped with-an integral head ll-having a cotter pin 12 ex` tending ytransversely. therethrough andv also through a brass stem 12 which yprojects medially through said head. Just tofone side of the center of the longitudinal extension of the stem 12 I provide an opening as 13, and at the outer extremity there is` still another opening 14, ,the said extremity nor` mally being seated in the' recess 15 ormed in the rearwall ofthe grease chamber, as clearly exhibitedlin F ig. 2 of the drawing. Eneirclingthe stem `12 is aspiral` spring16 which is adapted to engage the plunger 17 arrangedin close contact with a suit-able leather washer 18.

, In operation the chamber 3, is filled with grease, the pin 12 removed, and `the stem 12y withdrawn until the pin 19` normally positioned in the opening 14 engages the inner face of the washer 18, whereupon the stem 12 is further constrained outwardly against the tension of the coiled spring .16, until the opening 13 in the said stemy registers with the opening in the head 11 of 5, as will be seen in Fig. 3 of the drawing. 110

With vthe cornponent parts in the position just described the plug is screwed'into the chamber 3 and the split pin v12 'removed in order that the coiled "spring 16 may ex?" pand and thus force the lubricant `to the:V

aXle. Manifestly the lubricant will be ex? pelled into the passages 6 and 7y in direct contact Ywith the inajor portion of the ailev Q, while some of the grease'ivil-l passthrough the slot in communication With the passage 6 and onto the packing. Since the cohstructionand arrangement Vof the force feed lubricators are videnticah the foregoing ein y and 4inclo'sing the 'extended portion o'f the aXlef'isla pressedsteel cap 24, which, together with a rubber gaslet, 'are' fastened to 'the 'Wheel by a plurality ofbo'lts -26 which vproject entirely through ithe hub 'of 4the W'h'eel and -are secured' at their opposite `ends to the 'washer 26. It will thus beseenithat the packing 9 and (the rubber gasket 25, taken in conjunction With the pressed'steel cap 24: and Washer Q6', -:torni tivo lv'grease tight -joints Which prevent the'dripping and consequent Waste of the -g-',i*1"ease.` "It lwill *also be 'pointed `out that 'by reason 'of 'the particular fastening means `employed"for the pressed steel cap 24, the Wheel may be removedl orreplaced with facility, 'orthe'paeking 9 repaired or renewed vvithout -tl'e slightestcdificulty.

The advantages ofthe hereinbefore noted cnstruetionand arrangement fivill b'e" obvious Ato those skilledin the art.

A `Wheel 'constructedyin accordance :Wit-h my linvention has an Leasily accessible' fastening and bearing through lthe arrangenient of the pressedfste'el cap and Washer secured yto the Wheel :by 'means of the rbolts 20; an automatic, ypositive acting `grease chamber 'cast solid with the Wheel land Lar` ranged 'so that the stems which giiide ythe plungers used to force the lubricant from this chamber into the bearings, are atall 'um-@S within:daughtersanti@are fren ra- 'jury andapertures of novel shape and d1s- Iposition which lead from the grease charnber to the bearing, the same insuring a di- =rect yand plentiful lubrication of the full length of the bearing.
